Observations of the dynamic turbulence above La Palma using Stereo-SCIDAR (2015)
Journal Article
Osborn, J., Butterley, T., Perera, S., Fohring, D., & Wilson, R. (2015). Observations of the dynamic turbulence above La Palma using Stereo-SCIDAR. https://doi.org/10.20353/k3t4cp1131607

Stereo-SCIDAR is a generalised-SCIDAR instrument which is used to characterise the atmospheric optical turbu- lence in terms of strength (Cn2) and wind velocity profile using the triangulation technique and an optical binary star. Stereo-SCIDAR diffe... Read More about Observations of the dynamic turbulence above La Palma using Stereo-SCIDAR.

Atmospheric scintillation in astronomical photometry (2015)
Journal Article
Osborn, J., Föhring, D., Dhillon, V., & Wilson, R. (2015). Atmospheric scintillation in astronomical photometry. Monthly Notices of the Royal Astronomical Society, 452(2), 1707-1716. https://doi.org/10.1093/mnras/stv1400

Scintillation noise due to the Earth's turbulent atmosphere can be a dominant noise source in high-precision astronomical photometry when observing bright targets from the ground. Here we describe the phenomenon of scintillation from its physical ori... Read More about Atmospheric scintillation in astronomical photometry.

Characterising atmospheric optical turbulence using stereo-SCIDAR (2015)
Journal Article
Osborn, J., Butterley, T., Föhring, D., & Wilson, R. (2015). Characterising atmospheric optical turbulence using stereo-SCIDAR. Journal of Physics: Conference Series, 595(1), Article 012022. https://doi.org/10.1088/1742-6596/595/1/012022

Stereo-SCIDAR (SCIntillation Detection and Ranging) is a development to the well known SCIDAR method for characterisation of the Earth's atmospheric optical turbulence. Here we present some interesting capabilities, comparisons and results from a rec... Read More about Characterising atmospheric optical turbulence using stereo-SCIDAR.

Error sources in SLODAR turbulence profile fitting (2015)
Journal Article
Butterley, T., Osborn, J., & Wilson, R. (2015). Error sources in SLODAR turbulence profile fitting. Journal of Physics: Conference Series, 595(1), Article 012006. https://doi.org/10.1088/1742-6596/595/1/012006

This paper discusses some of the main error sources that affect use of the Slope Detection and Ranging (SLODAR) technique to recover atmospheric turbulence profiles from Shack-Hartmann wavefront sensor data. The most significant factor we address her... Read More about Error sources in SLODAR turbulence profile fitting.

Scintillation Noise in Exoplanet Transit Photometry (2015)
Journal Article
Föhring, D., Wilson, R., Osborn, J., & Dhillon, V. (2015). Scintillation Noise in Exoplanet Transit Photometry. Journal of Physics: Conference Series, 595(1), Article 012010. https://doi.org/10.1088/1742-6596/595/1/012010

Transit photometry is a powerful technique for studying exoplanets. Transit observations from the ground of targets of magnitude V= 10 or brighter, however, are limited by scintillation noise due to Earth's atmosphere. Through turbulence profiling us...

Characterising daytime atmospheric conditions on La Palma (2015)
Journal Article
Townson, M., Kellerer, A., Osborn, J., Butterley, T., Morris, T., & Wilson, R. (2015). Characterising daytime atmospheric conditions on La Palma. Journal of Physics: Conference Series, 595, Article 012035. https://doi.org/10.1088/1742-6596/595/1/012035

Day-time turbulence profiles are important for the next generation of Solar Telescopes, which will be equipped with multi conjugate adaptive optics systems. We measured daytime turbulence profiles above La Palma from 17th to 19th September 2013 using... Read More about Characterising daytime atmospheric conditions on La Palma.
